enzyme
The transformation from a solid to a liquid.
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.
Usually, there are two groups, a control group and an experimental group. For example, if you were showing how plants grow with fertilizer versus manure, the control group would be the fertilizer or the manure, depending on which you usually use. The experimental group would be the new substance, because you are experimenting on that. The control is what you give to the control group, if I am not mistaken. It is what you are not changing.
The control is what you're washing, amount of dirt, kind of dirt, temperature of water. The kind and amount of soap are variables, although when using the same kind in different amounts, the kind is control. The temperature of water is also control and variable depending on the test.
A thermostatic radiator valve is a valve that is connected to the hot water heating system. It can control the room temperature by regulating the amount of water that goes into the radiator. The valve is able to control this by sensing the temperature of the air.

You could have a runaway greenhouse effect, where positive feedbacks increase so rapidly that the temperature rises too fast and too high to control. Venus has a runaway greenhouse effect, and the oceans have boiled dry and the ground temperature is about 464 °C (867°F).
increasing energy Work increases the temperature of a substance due to friction.
No
When a substance is heated the temperature is increased. This occurs because energy enters the substance which will increase the kinetic energy of the molecules,thus causing a rise in temperature.
Room temperature is 25 oC so it would still be a solid. It would be 104 degrees F... So. unless the substance's boiling point is below that, it would be a solid. otherwise it would be a gas.
increasing energy
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
Temperature would be the typical answer.
That would be its temperature expressed in degrees of Fahrenheit, Celsius or centigrade.
You would use some type of thermometer.
